Answer:

y=0.25x

We can think of k as an unknown number.

8×_=2.00

12×_=3.00

20×_=5.00

If we divide 2 with 8 we are left with 0.25.

It's the same for the other numbers so we know the constant is 0.25.

When we use the formula y=0.25x with the numbers above, it is correct.

8×0.25=2.00

12×0.25=3.00

20×0.25=5.00

Graph the system of equations <br> 4x+4y=16<br> x+6y=-6

never [62]

Answer:

Graph has been shown in the attached file.

Step-by-step explanation:

We have been given the system of equations

$4x+4y=16.......(1)\\x+6y=-6.........(2)$

Both the equation represents a straight lines. We can find the x and y intercepts of these lines to graph.

The intercept form of a line is given by

$\frac{x}{a}+\frac{y}{b}=1$

Here a is the x - intercept and b is the y-intercept.

Divide both sides of the equation (1) by 16

$\frac{4x}{16}+\frac{4y}{16}=1\\\\\frac{x}{4}+\frac{y}{4}=1$

Hence, x-intercept = 4 and the point is (4,0)

y-intercept = 4 and the point is (0,4)

Similarly, for the second line

Divide both sides of the equation (2) by -6

$\frac{x}{-6}+\frac{6y}{-6}=1\\\\\frac{x}{-6}+\frac{y}{-1}=1$

x-intercept = -6 and the point is (-6,0)

y-intercept = -1 and the point is (0,-1)

We'll plot these points in the xy- plane and then join to get the graph of these lines.

Diana has 18 apples more than Roberto. Together, Diana and Roberto's apples are 48. How many apples does each have?

Hitman42 [59]

Answer:

Diana has 33 and Roberto has 15.

Step-by-step explanation:

Use D for the amount of apples Diana has and R for Roberto

D=R+18

D+R=48

Use Substitution to solve the system of Equations

R+18+R=48 ----> 2R+18=48- Subtract 18

2R=30- DIvide by 2

R=15

Substitute R into another equation

D=R+18

D=15+18

D=33
